Sean Anderson 8c05f14b58 Order ports with default assignments first 
Although the current style is allowed by the standard, Icarus verilog
doesn't parse default assignments using an implicit net type:

	techlibs/ice40/cells_sim.v:305: syntax error
	techlibs/ice40/cells_sim.v:1: Errors in port declarations.

Fix this by making sure that ports with default assignments first on
their line.

Fixes: 46d3f03d2 ("Add default assignments to other SB_* simulation models")

anlogic: support BRAM mapping
 2022-01-19 08:49:58 +01:00
Lofty d015c2b48a intel_alm: disable 256x40 M10K mode 
This BRAM mode uses both address ports, making it effectively single-port.
Since memory_bram can't presently map to single-port memories, remove it.
 2021-12-22 00:42:33 +01:00
Icenowy Zheng c2b7ad3b28 anlogic: support BRAM mapping 
Anlogic FPGAs all have two kinds of BRAMs, one is 9bit*1K when being
true dual port (or 18bit*512 when simple dual port), the other is
16bit*2K.

Supports mapping of these two kinds of BRAMs. 9Kbit BRAM in SDP mode and
32Kbit BRAM with 8bit width are not support yet.
